Sharpening techniques

Concrete: Putting an edge on carbide bits, silicone carbide or diamond tooling is most commonly used. The design of these bits are to chisel - breaking the hard concrete - the spiral designs are for waste removal. What I'm trying to say is the sharp edge is to break the concrete into small enough pieces so as to easily remove the waste creating a hole. Diamond concrete cutting blades can load up and not cut. I've been told - pumas block being very soft. Cutting through it will open up the diamond cutters. ****please note concrete dust and particles to us if breathed in are dangerous - it's a mineral and doesn't just go away - a must is to use protection. Metals cutting tools: The cutting of different metals can get complicated. With bits their sharpening is best done by sharpening services. The angles and relief's are to difficult for me to maintain. There are good and bad sharpeners. Chose with care.

Wood cutting tools

The tools are normally made of either steel or carbide. Steel chisels and hand planer blades. I like to use Japanese wet stones for honing. The front and back sides of these tools need polishing to a mirror finish removing all tooling marks. My finest grit stone is 6000. This puts a fantastic edge on the tools.

Carbide tipped saw blades

The professional sharpening service again. They are going to use diamond wheels. Different sizes shapes and grits. Our local service goes up to 1000 grit. (one thousand grit)That is sharp when it comes to saw blades. Normally what I'm use to is 600 grit grind for the finer quality blades. Note, when you purchase saw blades try to find out the grind grit. It will make your job a lot easier with the sharpest blades. Single spur/single flute. Double spur and single may be incorporate with a double flute. Lead cutter lip to reduce chipping. Single, one cutter. Double, two cutters. The flutes can be coated with molybdenum. This reduces friction, keeping the heat down, making the drilling process easier. Users do like this. Nail cutting vs. non nail cutting. Extra hardened and or alloyed special steels. Sharpening is normally done with an auger bit file or extra slim taper files and sometimes diamond files. Shafts are normally hex in shape. Basin bits are becoming less available. Quick change shanks are becoming more common. Extra length shafts for accommodating counter bores.
